How to use the return value of a function with parameters inside another function

Question

All these functions are outside the int main():

int func1(int x) {

    int v1 = 6 * x;
    return v1; // the input argument will be 2, so v1 = 12
}

int func2()         


        

Answer 1

Could you clarify your question? From my understanding you're doing what you want correctly.

double add_5(double x) {
    return x + 5;
}
double nested_method(double x) {
    double myVariable = add_5(x); //my variable = x + 5
    //other code//
    return myVariable;
}
int main() {
double myInput = 123;
    std::cout << nested_method(myInput) << std::endl; //output should = 128
}

If a method asks for 'n' parameters to call the method you must give it each of those 'n' parameters (of the apropriate type).

ignoring overloads / default values etc
